Insulation

Insulation slows heat. It does its job once the air has stopped moving through it, so it comes second.

The report names where the house is under-insulated and what each place is made of. Loose-fill suits an open attic. Dense-pack suits a closed wall cavity. Rigid board or spray foam suits a rim joist or a sloped ceiling. We pick for the house.

What's included

  • Attic floor or sloped ceiling insulation

  • Dense-pack for closed wall cavities, where the report calls for it

  • Rim joist and basement ceiling insulation

  • Baffles to keep soffit vents open

  • A clear note on moisture and vapor control

  • A walk-through at the end, with photos

Cost

What changes the price

  • What is already there

    Old insulation may need to be taken out first, especially if it is wet or contaminated.

  • The material

    Cellulose, fiberglass, mineral wool, rigid foam and spray foam each cost differently.

  • Depth

    More depth costs more, and the benefit of each added inch gets smaller. The report shows the trade.

  • Access

    A big open attic is quick. A low roof, a knee wall or a closed cavity is slower.

  • Moisture

    Wet or moldy framing is fixed before anything covers it.

How it goes

This work, in order

  1. 01
    Day one

    Step 1: The look

    We open the attic hatch and check the walls with a camera before we quote. The report says what is there.

  2. 02
    On site

    Step 2: Prep

    Seal the air leaks first. Set baffles at the eaves. Protect wiring and recessed lights.

  3. 03
    On site

    Step 3: Install

    Blow, pack or spray, to the depth in the estimate. We mark depth where you can read it.

  4. 04
    Last day

    Step 4: The last check

    We walk it with you, photograph the work and send the photos with the invoice.

Not included

What this work leaves out

  • Abatement of lead paint or asbestos

    If we find something we can't handle safely, we stop and tell you who can.

  • A promised savings figure

    We don't promise a bill. Your heating costs depend on fuel, weather and how you live.

  • Rebate paperwork

    Incentives change. We tell you which programs the work could fit; you apply, or we help you read the form.

Before the work

Permits and rules

Adding insulation to an existing home usually needs no permit. Closing in a chimney or changing a roof's ventilation can. We ask the town when it matters and tell you what we learned.

Painted surfaces in houses built before 1978 may hold lead. If the work will disturb them, we follow EPA's lead paint rule; see the certificate and insurance page.

Questions about this work

Is spray foam better than cellulose?

It depends on the place. Each has places it suits. The report names the product and why.

Will insulation cause moisture problems?

Done wrong, it can. That is why air sealing comes first, and why we check for moisture before closing anything up.

Can you insulate an old stone or brick house?

Often, with care. These walls dry in both directions, and some materials can trap moisture. We say plainly when we'd leave a wall alone.

Do I have to be home?

Not usually. We need access to the attic and basement and a clear path to the work.
